Understanding Case Styles
Different contexts require different capitalization rules:
UPPERCASE
Every letter capitalized. Used for acronyms (NASA, FBI), emphasis, or headlines. Can feel aggressive in body text.
lowercase
No capitals at all. Common in modern branding (adidas, iphone) and casual internet writing. Breaks traditional grammar rules.
Title Case
Capitalizes major words. Perfect for headlines, book titles, and article names. Example: "The Art of War"
Sentence case
Only the first word of each sentence is capitalized. This is standard paragraph writing.
Content Writers

Frequently Asked Questions
Does it preserve line breaks?
Yes. The tool maintains your paragraph structure, indentation, and spacing while only changing letter case.
What about proper nouns?
The tool applies rules mechanically—it doesn't know that "paris" should be "Paris" (the city) vs "paris" (lowercase for effect). You may need to manually fix proper nouns after conversion.
Can I convert multiple paragraphs at once?
Absolutely. Paste as much text as you want. The tool processes everything instantly, regardless of length.
Style Guide Note
Different style guides (AP, Chicago, MLA) have slightly different Title Case rules. Our tool uses a common standard that capitalizes all words except articles and short prepositions.
